Jenifer is flying her kite and it gets stuck in a tree. She knows the string on her kite is 16 feet long and she is 4 feet from the tree.
Answers
Answer: 15.49 ft
Step-by-step explanation:
The rest of the question is:
How long of a ladder (in feet) will she need to get her kite out of the tree? Enter your answer as a decimal rounded to two decimal places.
The scenario described forms a right angle triangle where:
Hypothenuse = 16 ft
Base = 4 ft
Height is the length of the ladder
This can be solved by the Pythagorean expression:
c² = a² + b²
Where:
c = hypothenuse
a = base
b = height
16² = 4² + b²
b² = 16² - 4²
b² = 256 - 16
b = √240
b = 15.49 ft

Stephanie put $80 in her bank account when she was 5
years old. The bank gave her a simple interest rate of 2.1%.
Does she have enough money to buy a TV for $1,000 after
leaving her money in the bank for ten years?
Answers
Answer:
Mynd44
Step-by-step explanation:
Here, we want to check if the amount of money saved is enough to
by a tv
Mathematically, we have the simple interest formula as follows;
I = PRT/100
I = (80 * 2.1*10)/100
I = 1680/1000 = 1.68
Hence, she will not have enough

A recommendation for wheelchair ramps is that the rise-to-run ratio be no greater than 1:12. This ensures that the ramps are navigable by people in wheelchairs. If a business needs to install a concrete ramp to the entrance of their building, which is 12 inches off the ground, how long should the ramp be and how far out horizontally on the ground will it protrude from the building? Give answers in feet and inches, such as 5 feet, 4 inches. What percent grade is the ramp?
Answers
Answer:
a. 12 feet b. 12 feet 0.5 inches c. 8.33 %
Step-by-step explanation:
a. How far out horizontally on the ground will it protrude from the building?
Since the rise to run ratio is 1:12 and the building is 12 inches off the ground, let x be the horizontal distance the ramp protrudes.
So, by ratios rise/run = 1/12 = 12/x
1/12 = 12/x
x = 12 × 12
x = 144 inches
Since 12 inches = 1 foot, 144 inches = 144 × 1 inch = 144 × 1 foot/12 inches = 12 feet
b. How long should the ramp be?
The length of the ramp, L is gotten from Pythagoras' theorem since the ramp is a right-angled triangle with sides 12 inches and 144 inches respectively.
So, L = √(12² + 144²)
= √[12² + (12² × 12²)]
= 12√(1 + 144)
= 12√145
= 12 × 12.042
= 144.5 inches
Since 12 inches = 1 foot, 144.5 inches = 144 × 1 inch + 0.5 inches = 144 × 1 foot/12 inches + 0.5 inches = 12 feet 0.5 inches
c. What percent grade is the ramp?
The percentage grade of the ramp = rise/run × 100 %
= 12 inches/144 inches × 100 %
= 1/12 × 100 %
= 0.0833 × 100 %
= 8.33 %

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first equation be = A
Let the second equation be = B
Now , we have two equations
4x + 3y = 5 be equation (1)
2x + 3y = 1 be equation (2)
Now , on simplifying the equations , we get
Subtracting equation (2) from equation (1) , we get
2x = 4
Divide by 2 on both sides , we get
x = 2
Substitute the value of x in equation (1) , we get
4 ( 2 ) + 3y = 5
8 + 3y = 5
Subtract 8 on both sides , we get
3y = -3
Divide by 3 on both sides , we get
y = -1
Therefore , the value of x and y is 2 and -1 respectively
Hence , The value of x = 2
The value of y = -1

Find the area of all shaded regions. Give your answer as a completely simplified exact value in terms of pi. (no approximations)
Answers
To find the area of the shaded region, you first use the equation A = πr²
The radius of the circle is 9 cm. So A = π(9²)
A = 3.14 (81)
A = 254.34 (entire circle)
The entire circle is 360°
and 4.5 of the 80°'s will equal 360°
254.34 ÷ 4.5 = 56.52
ANSWER: 56.52 cm²
Answer:
56.55 cm^2
Step-by-step explanation:
Since a circle is 360 degrees and the piece is 80 degrees, the shaded area is 4.5 of the total area of the circle (9/2). Find the area of the circle:

Amy and Roger both wash windows at a large downtown building. Amy can wash 25 windows In 4 hours, Roger can wash 32 windows in 6 hours. How many windows can they wash together in 12 hours? [Type your answer as a number.)
Answers
Answer:
139 windows
Step-by-step explanation:
you multiply the 25 by 3 because Amy washes 25 windows per 4 hours and 3x4 is 12 so that would be 75 then you multiply the 32 by 2 because 6x2 is 12 so that would be 64 then you add the 64 and 75 which would give you 139 windows for both of them in 12 hours
